ADF4002SRUZ-EP

Overview

The ADF4002SRUZ-EP is an enhanced product phase detector and frequency synthesizer designed for defense and aerospace applications. It operates within a military temperature range of −55°C to +125°C and supports a 400 MHz bandwidth with a 2.7 V to 3.3 V power supply. The device integrates a low-noise digital phase frequency detector (PFD), a precision charge pump, and programmable reference and N dividers. Key electrical specifications include a maximum RF input sensitivity of 0 dBm, a PFD frequency up to 104 MHz, and programmable charge pump currents ranging from 625 µA to 5 mA. It features a separate charge pump supply (VP) to allow extended tuning voltages in 3 V systems.

Feature Summary

• Military temperature range operation from −55°C to +125°C
• Supports defense and aerospace applications under AQEC standard
• Controlled manufacturing baseline with one assembly/test site and one fabrication site
• Programmable charge pump currents (625 µA to 5 mA) and separate VP supply

Applications

• Clock conditioning
• Clock generation
• IF LO generation in wireless receivers and transmitters

Procurement Notes

Verify the specific ordering suffix (RU vs RUZ) against the datasheet's Ordering Guide to confirm RoHS compliance status. Ensure that the required environmental qualification data is requested directly from Analog Devices, as this information is available upon request for the EP series. Confirm that the controlled manufacturing baseline meets specific project traceability requirements.

Selection Notes

Select the ADF4002SRUZ-EP when military-grade reliability and wide temperature operation are required. The device supports a 400 MHz input frequency range and offers a 104 MHz PFD frequency. Designers must account for the separate VP supply requirement, which can be set up to 5.5 V to drive VCOs with higher tuning voltages while maintaining a 3 V logic supply.

Part Context

The ADF4002SRUZ-EP is the enhanced product variant of the standard ADF4002 frequency synthesizer. It shares the same core functional architecture but is qualified for harsh environments. The 'SRU' indicates the 16-lead TSSOP package, while 'Z' denotes RoHS compliance. This part is distinct from the ADAR4002, which is a modulator/demodulator component.

Replacement Considerations

The standard commercial ADF4002BRUZ serves as the non-military counterpart. Substitution requires verifying that the industrial temperature range (-40°C to +85°C) and commercial manufacturing baseline are sufficient for the application environment.
